POLYPHASE STATOR FOR AN INTERNALLY VENTILATED ROTATING ELECTRICAL MACHINE, AND ROTATING ELECTRICAL MACHINE COMPRISING SUCH A STATOR |
摘要 |
<p>A polyphase stator for an internally ventilated rotating electrical machine comprises a body (14) provided with slots and carrying a coil (12) having at least one winding per phase. A plurality of pairs of lateral branches are mounted in a slot of the body (14). A plurality of connecting heads (50 to 55) extend outside the body (14) so as to form a first lead-out (42) and interconnect each pair of lateral branches. A plurality of coupling feet (150 to 155) are offset circumferentially with respect to the plurality of connecting heads and extend outside the body (14) so as to form a second lead-out (43) and interconnect each pair of lateral branches. One of the pluralities has a generally pointed shape and has an axial length of between 15 and 20 mm. The stator is used with an alternator or alternator-stator for a motor vehicle. An internally ventilated electrical machine is equipped with the stator.</p> |
